The accuracy of the . 44 Magnum is very good, with models from Colt, Smith & Wesson, and Ruger producing bullet groups of 3 to 4 inches (7. 6 to 10. 2 centimetres) at 50 yards (46 m), with most ammunition. The limiting factor of the . 44 Magnum cartridge is not terminal ballistics. When fired from a 6 in (150 mm) revolver, a typically loaded . 44 Magnum 240 gr (16 g) bullet will have more impact energy at 150 yd (140 m) than a 246 gr (15. 9 g) . 44 Special has at the muzzle, when fired from the same weapon. When loaded with a heavy, non-expanding bullet, the . 44 Magnum will easily shoot through large game such as elk and even bison. The limiting factor is the bullet's trajectory; the best hunting bullets are heavy, so relatively slow, meaning a significant drop-out of trajectory at ranges beyond 100 yards (91 m); with a 50 yd (46 m) zero, the point of which the "line of sight" and the "bullet trajectory" meet, drop-out at 100 yd (91 m) is about 2 inches (5. 1 centimetres), and drop-out at 150 yards (140 m) is more than 8 inches (20 centimetres); with a 100 yd (91 m) zero, drop-out at 150 yd (140 m) is more than 6 inches (15 centimetres). Experts recommend limiting hunting ranges to 100 yards (91 m) when shooting . 44 Magnum cartridges, less if practical accuracy requires it.
